This is" appareaa data-a by the bendingpin in its return movement, and the chief purpose of he present invention is to replace the wires in their former straight line, in case they have been bent out of shape. The mechanism for doing this consists of an attachment for the eye-forming devices, such as are shown in said former patent. Certain parts of the original machine have been included in the present drawings, tobetter illustrate the invention, and show the relation of the parts to those of the former machine.

In the drawings Fig. 1 is a front elevation, showing parts of said former machine, as disclosed in Fig. 23 of said patent, with the present invention applied thereto.

Fig. 2 is a plan view of the invention, detached.

Fig. 3 is a face view the end of the jaw C.

The parts of the former machine are indicated in the drawing in capital letters, said parts including a support or base-block A, carrying the lower stationary vise B, and a rockably mounted jaw C, in which is mounted aclamping die D. The jaw C is pivoted in the base A, as at a, and is designed to be rocked upwardly, to release the tie thereof, looking at wire, after the eye is formed in the end thereof, by means of mechanism set forth in said former patent, and not specially involved herein. A bearing E is supported in the machine, in which is journaled a shaft F, 011 the end of which is a twisting mechp 2, connected by a anism G, and opeaavay r mmed on the block A eaten-ding pir'i crank H, adapted. to mm a loopiii the endof the wire. During this operation the wire, shown at i1, is looped round the pin G of the twisting deVices after which said pin is withdrawn and, the? bending-pin}? rename to its former position, evidently coming in I contact with the looped end of the wire and bending the same. The arrangement and timing of tl' eiopeiating' devi ce'sis' such that immediately tol-lowingthe' forminj of the eye i'n the of the wife the jaw is rocked upward 1y, so as to permit at release of the wire. This upward nioveinent of the jaw is made use of in'operating the attachment, the parts of-whi'ch are as fellowsze Secu'red to the topjof the jawC is aplateupomwhi'ch is slidably mounted aplate 7 rod swish a bracket 4, supported on the hearing E, The plat 2 is'recfes'sed, aiid rovided at] one end thereof with" scam" face 5, in engagement with the upper end of a lever 6, fulcrumed in a recess 7 in the plate 1, as at b. The lower end of said lever is connected with a bar 8, extending transversely of the lower face of the jaw C, and slidably supported at its other end in a hanger 9, depending from the plate 1. Projected downwardly from the bar 8 is a cam-shaped member 10, at one side of the wire 11, when in position in the jaws of the machine. A contractile coiled spring 12 connects the upper end of the lever 6 with a post 13, fixed on the plate 1, the purpose of said spring being to return said lever to its normal position, with the cam member in contact with the wire 11, as shown in Fig. 3.

\Vhen the jaw C is in a lowered position the inclined edge 5 is in position to force the upper end of the lever 6 outwardly, movmg the bar 8 to carry the cam 10 outwardly, so as not to interfere with the movement of-the wire 11. After the twisting operation, as the jaw C is elevated, the distance between the upper end of the lever 6 and the post 4 is shortened sufficiently to permit a return movement of such upper end to the inner 'end of the recess 7, this movement being impelled by the spring 12. This takes place as the jaw is being raised, and in this movement the cam 10 is brought inwardly into contact with the wire, If such wire has been bent out of a straight line in the direction of the cam 10, the return action of said cam serves to force such wire back into a straight line.

To facilitate the operation of the parts, the rod 3 has a pivotal connection with the plate 2, the operation of the plate 2 being the same as it would be if the jaw C were in a fixed position, and the bracket i movable with relation thereto.

The engaging edge of the cam 10 is curved to prevent the same from carrying the wire upwardly in the upward movement of the jaw C and appurtenant parts. a

hat, I claim. and desire to secure by Letters Patent, is:

1. In combination with the frameof a bale-tie machine, and a pair of wire-gripping jaws supported therein, one of which is rockably mounted with relation to the other, a wire straightening cam, movable beneath said rockable jaw, transversely thereof, a fixture supported on the frame, in proximity to said last-named jaw, and means connected with said fixture for actuating said. wire straightening cam upon said last-named jaw being suitably rocked.

2, In combination with the frame of a bale-tie machine, and a pair of wire-grip ping jaws supported therein, one of which is rockably mounted with relation to the other, a wire-straightening cam movable beneath said rockable aw, transversely thereof,

a plate slidable on said jaw, at right angles with said wire straightening cam, a fixture supported on said frame, means connecting said slidable plate with said fixture, and means for imparting the movement of said slidable plate to said straightening cam, to cause the same to operate upon said rockable jaw being suitably actuated.

3. In combination with the frame of a bale-tie machine, and a pa1r of w1regripping jaws supported therein, one of which jaws is rockably mounted with relation to the other, a fixture on the frame in proximity to said lastnamed jaw, a wire straightening cam operable beneath said last-named jaw, transversely thereof, a lever fulcrumed at one side of said last-named jaw and operativcly connected with said wire straightening cam, a slide-plate mounted on said lastnamed jaw, having a positive connection with said fixture, and in engagement with said lever' to move said wire straightening cam out of operative position upon said rockable jaw being moved toward the fixed jaw, and means for returning said straight ening cam to an operative position upon said. rockable jaw being moved away from said fixed jaw.

In testimony whereof I aflix my signature.

ROY HEWITT.
